(1) Other bonds include asset-backed securities.

(2) Comprised of 759 and 757 individual securities as of March 31, 2024 and December 31, 2023, respectively.

​

The Company has evaluated AFS securities in an unrealized loss position for credit related impairment at March 31, 2024 and December 31, 2023 and concluded no impairment existed based on several factors which included: (1) the majority of these securities are of high credit quality, (2) unrealized losses are primarily the result of market volatility and increases in market interest rates, (3) the contractual terms of the investments do not permit the issuer(s) to settle the securities at a price less than the cost basis of each investment, (4) issuers continue to make timely principal and interest payments, and (5) the Company does not intend to sell any of the investments and the accounting standard of “more likely than not” has not been met for the Company to be required to sell any of the investments before recovery of its amortized cost basis.

Additionally, the majority of the Company’s MBS are issued by FNMA, FHLMC, and GNMA and do not have credit risk given the implicit and explicit government guarantees associated with these agencies. In addition, the non-agency mortgage-backed and asset-backed securities generally received a 20% simplified supervisory formula approach rating. The Company’s AFS investment portfolio is generally highly-rated or agency backed. At March 31, 2024 and December 31, 2023, all AFS securities were current with no securities past due or on non-accrual and no ACL was held against the Company’s AFS securities portfolio.

​

​

The following table presents the amortized cost and estimated fair value of AFS securities as of the periods ended, by contractual maturity (dollars in thousands). Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Refer to Note 7 “Commitments and Contingencies” within this Item 1 of this Quarterly Report for information regarding the estimated fair value of AFS securities that were pledged to secure public deposits, repurchase agreements, and for other purposes as permitted or required by law as of March 31, 2024 and December 31, 2023.

Accrued interest receivable on AFS securities totaled $9.1 million and $9.5 million at March 31, 2024 and December 31, 2023, respectively, and is included in “Other assets” on the Company’s Consolidated Balance Sheets. For the three months ended March 31, 2024 and 2023, accrued interest receivable write-offs were not material to the Company’s consolidated financial statements.

Held to Maturity

​

The Company reports HTM securities on the Company’s Consolidated Balance Sheets at carrying value. Carrying value is amortized cost, which includes any unamortized unrealized gains and losses recognized in AOCI prior to reclassifying the securities from AFS securities to HTM securities. The carrying value, gross unrealized gains and losses, and estimated fair values of HTM securities for the periods ended are as follows (dollars in thousands):
